Q:

Write a program for matrix multiplication in c

Answer

#include <stdio.h>


int main() {


  int a[5][5], b[5][5], c[5][5], i, j, k, sum = 0, m, n, o, p;


  printf( "\nEnter the row and column of first matrix" );


  scanf( "%d %d", &m, &n );


  printf( "\nEnter the row and column of second matrix" );


  scanf( "%d %d", &o, &p );


  if(n!=o) {


      printf( "Matrix mutiplication is not possible" );


      printf( "\nColumn of first matrix must be same as row of second matrix" );


  }


  else {


      printf( "\nEnter the First matrix" );


      for( i=0; i<m; i++ )


      for( j=0; j<n; j++ )


           scanf( "%d", &a[i][j] );


      printf( "\nEnter the Second matrix" );


      for( i=0; i<o; i++ )


      for( j=0; j<p; j++ )


           scanf( "%d", &b[i][j] );


      printf( "\nThe First matrix is\n" );


      for( i=0; i<m; i++ ) {


      printf("\n");


      for( j=0; j<n; j++ ) {


           printf( "%d\t", a[i][j] );


      }


      }


      printf( "\nThe Second matrix is\n" );


      for( i=0; i<o; i++ ) {


      printf("\n");


      for( j=0; j<p; j++ ) {


           printf( "%d\t", b[i][j] );


      }       


      }

      for( j=0; j<p;j++ )


           c[i][j] = 0;


      for( i=0; i<m; i++ ) { //row of first matrix


      for( j=0; j<p; j++ )  {  //column of second matrix


           sum = 0;


           for( k=0; k<n; k++ )


               sum = sum + a[i][k]*b[k][j];


           c[i][j] = sum;


      }


      }


  }


  printf( "\nThe multiplication of two matrix is\n" );


  for( i=0; i<m; i++ ) {


      printf("\n");


      for( j=0; j<p; j++ ) {


           printf( "%d\t", c[i][j] );
